1 b all whom it may concern Be it known that I, BASIL SANER, a citizenof the United States, and residing at West New York, in the county ofHudson. and State of New Jersey, have invented certain new and usefulImprovements in Embroidering-Machines, of which the following is aspecification, such as will enable those skilled in the art to which itappertains to make and use the same.

This invention relates to cmbroidering machines, and particularly toWhat are known as Swiss and German embroidering machines, and the objectthereof is to improve a machine of this class by doing away with theshuttle and bobbin devices and the mechanism for operating the same, andsubstituting therefor a novel stitch forming mechanism whereby theoperation of embroidering any design on a cloth or fabric may beperformed with a single thread where two have heretofore been employed,and whereby an improved lock-chain stitch is formed which consists of asingle thread on one side of the cloth or fabric and a double thread onthe opposite side of the cloth or fabric, and whereby both theconstruction and operation of the machine is cheapened and simplifiedand the operation and results produced improved, and with this and otherobjects in view the invention consists in an embroidering machine of theclass specified constructed and operating as hereinafter described andclaimed.

The invention is fully disclosed in the following specification of whichthe accompanying drawing forms a part, in which the separate parts of myinvention are designated by suitable reference characters in each of theviews, and in which Figure 1 is a transverse sectional view through anembroidering machine of the class specified, but showing only certaindetails of the machine as originally constructed and my improvements inconnection therewith ;-Fig. 2 a rear view of the construction shown inFig. 1, Fig. 3 a plan view of the construction shown in Fig. 2 withcertain parts omitted ;Fig. i a fragmentary view similar to Fig. 1 butshowing the parts on an enlarged scale and in a diflerent position;Fig.5 a front view of a part of a cloth or fabric sheet, and showing a lineof stitches produced by a single needle and a corresponding looper hook;Fig. 6 a view similar to Fig. 5 but showing the reverse directed arms fside of the cloth or fabric sheet; Fig. 7 a side view of a part of afinger bar which I employ, and Figs. 8 to 16 inclusive are detail viewsshowing different steps in the process of forming a lock-chain stitch.

In the accompanying drawing, I have shown only such parts of theoriginal machine as are necessary to illustrate and describe theconstruction and operation of my improvement, and in Figs. 1, 2 and 8 ofthe accompanying drawing, I have shown at a the shuttle bar of a machineof the class specified, or the bar in connection with which the ordinaryshuttles have heretofore been mounted, and it will be understood thatthis bar is stationary and extends from one end of the machine to theother. I have also shown at b the presser finger bar which carries thepresser fingers b and the bar Z) has a slight rotary movement inopposite directions and extends the full length of the machine, and thisbar with its fingers b are the same as in the original machine, and inpractice, a large number of the fingers b are employed. I have alsoshown at c the usual needle bar which also extends the full length ofthe machine, and is provided with the usual needle brackets 0 having theusual needles c and the bar 0 has a forward and backward movement, andthe needle brackets c and needles 0 correspond in number with thepresser fingers 6 I have also shown at d the borer bar which extends thefull length of the machine, and has a forward and backward movement, andwhich is provided with the usual borer needles d which are arranged inpairs in separate vertical planes, between the presser fingers I2 I havealso shown at e and e the ordinary thread guide rods which extend thefull length of the machine and over and around which the threads 6 arepassed, and it will be understood that a thread a is employed inconnection with each of the needles c and the thread guide rods 6 and 6also have a forward and backward movement, in the operation of the machine, in order to take up or regulate the slack or tension of thethreads 6 and it will be understood that each of the threads 0 is woundon a bobbin suitably supported at the front of the machine in the usualmanner.

Supported at the back of the machine and at the rear of the shuttle bara are a plurality of equally spaced bell cranks f having downwardlydirected arms f and laterally The supports of these bell cranks areindicated at f, in Fig. 2 only, but it will be understood that thesebell cranks form a part of the old machine and are supported in theusual manner.

The laterally directed arms f of the bell cranks f are forked, theseparate members of said arms being shown at f in Fig. 1, and mounted inthe forked ends of said bell cranks are pins f, and mounted on the pinsf are links 9 having forked heads through which are passed pins 9 andmounted on the pins g in the forked heads of the links 9 are bars 9 Inthe original machine the parts a, 7), 0 and (Z with their connectionsare all duplicated, one series of said parts being above the other, andthe bars extend upwardly and are connected with the upper series of saidparts so that the said series are operated simultaneously, and it willbe understood that the bell cranks f and the parts f, g and g are all ofthe usual construction, and there is one of the bars 9 employed inconnection with each of the bell cranks f and said bell cranks areoperated by a hori- Zontally reciprocating rod 9 in the usual manner.

In the practice of my invention, I secure to the top of the shuttle bara and trans versely thereof a series of brackets it which correspond innumber with the cranks f and are provided with raised, backwardlydirected heads k in which are mounted vertically arranged pins 713.

The inner ends of the pins g are provided with heads M in which thelower ends of the pins 71, are secured, and secured to the upper ends ofthe pins h is a bar 2' which extends the full length of the machine, andin the operation of the machine the pins g and k are given a verticalmovement as is also the bar 2'.

The bar i is provided with a plurality of backwardly directed looperhook supportingarms 7? which correspond in number with the needles c andeach of these arms is provided with a vertically arranged looper hook 2'comprising a vertical shank portion 2' and downwardly directed hookmembers composed of spring or resilient mate rial and having an inwardlydirected point 71 between which and the shank, under normal conditions,is a space 5. The end of the arms '5 are provided in their ends withcurfs, as shown at i in which the shanks a of the looper hooks i aresecured by a clamp screw or in any other suitable way. I also provide acloth plate 7' which extends the full length of the machine and issecured to the brackets h in a vertical position corresponding with theposition of the presser fingers b and between which and said fingers thecloth or fabric 7' to be operated upon, or embroidered, is placed orsupported and make movable in the usual manner.

The plate j is provided with a plurality of apertures which are arrangedin horizontal and vertical rows, and the apertures in the vertical rowsare three in number, the top apertures being for the needles 1 and thebottom apertures being for the borers (I Secured to the back face of thecloth plate 7' between the upper horizontal rows of apertures arebrackets j in. which is mounted a longitudinally intermittentlyreciprocating finger bar provided with a plurality of fingers 70 whichcorrespond in number with the looper hooks 2' and the needles c andoperate in connection therewith as hereinafter described, and thefingers k are composed of vertically arranged shank members andlaterally directed, inclined puller hook members 7,1. I have also shownat m the main drive shaft of the machine and in the practice of myinvention, I gear in connection therewith a horizontal cam shaft m thisconstruction being clearly shown in Fig. 3, and this shaft is pro-videdwith a cam disk m, and at one side of the cam shaft mi is a bracket into which is pivoted a cam operated lover a. The lever n is provided withan anti-friction roller 11 in connection with which the cam in oierates, and the upper end of said lever is provided with. a link itwhich is pivoted at 12; to the finger bar 7:, and the lever n is alsoprovided with a pull spring 17, which normally holds the roller n inengagement with the cam 211..

At the ends of the cloth plate j are brackets 0 in which is supported ahorizontal hook closing bar 0 which lies in a plane beneath that of theneedles 0", as clearly shown in Figs. 1, 2 and 4, and said bar isadjustable vertically in the brackets 0 by means of set screws 0 or inany other suit able way.

The upper ends of the puller fingers b are provided with inwardly setparts 12 and the upper edge portion of the cloth plate j is providedwith corresponding inwardly set longitudinal portions y between whichthe cloth or fabric sheet j is held and immediately below which theneedles operate, and the object of this construction is to hold saidsheet in proper position without interfering with the movement thereof.

In the operation of the machine the needles 0 are threaded in the usualmanner, and the position of the cloth or fabric sheet 7' adjusted asdesired. It will be understood that the fabric sheet 7' to beembroidered is supported in a frame which extends the full length of themachine and which is operated by a pantograph device in the usualmanner, said frame and pantograph being not shown. It will also beunderstood that the borers or borer needles operate in the same manneras in other machines of this class, and in their operation pass throughthe corresponding apertures j in the plate j.

In the first movement of the various parts of the machine in thebeginning of the process of embroidering, the needles 0 and looper hooksi are thrown into the position shown in Fig. 8, which is the positionassumed at the beginning of the formation of a stitch, and at which timethe needles 0 are at the limit of their projection through the clothplate, and the looper hooks are in their lowest position caused byrocking the bell cranks f through the rod 9 The planes of the looperhooks i are parallel with and at one side of the planes of the needlesand in the second step or movement in the formation of a stitch orstitches, the needles are drawn backwardly, as shown in Fig. 9, or inthe direction of the front of the machine and the loops p are formed inthe threads on the back sides of the cloth plate y. In the next step ormovement the looper hooks i are raised as shown in Fig. 10, while theneedles remain stationary and the hook members of the looper hooks arepassed vertically through the thread loops 7), and in the next movementor step, as shown in Fig. 11, the looper hook remains stationary whilethe needle points are drawn farther back and the loops 79 are drawntightly around the shanks of the looper hooks. In the next step ormovement, as shown in Fig. 12, the needles are entirely withdrawn fromthe cloth plate j and the looper hooks are drawn back into their lowestposition, and in this operation the thread loops 2? pass into the bottomof the hook members of the looper hooks and are drawn downwardly belowthe plane of the needles and below the hook closing bar or rod 0 In thenext step or movement, as shown in Fig. 13, the bar is moved to theright and the puller fingers 70 are also drawn to the right and the hookmembers 70 thereof pass over the thread loops 0, as shown in Figs. 1, 1and 13, and at the same time the needles 0 are projected again, as shownin Figs. 8 and 13, and in the next step or movement, as shown in Fig.14, the needles are partially drawn back and the looper hooks raisedthus forming new thread loops 19 through which the looper hooks i arepassed while the fingers k remain as shown in Fig. 13. In the next stepor movement the needles are entirely withdrawn and the puller fingers kare moved to the left and withdrawn from their engagement with thethread loops 9, and the looper hooks 2' assume the position shown inFig. 15, and in this operation the bar 0 closes the hooks 2' by pressingthe points thereof inwardly against the shanks i of the looper hooks 2'and as the looper hooks 2' descend, as shown in Fig. 16, the loops pride up over the hooks i and are drawn backwardly through the clothplate, as indicated in said figure, and as this operation continues, thestitches 29 shown in Figs. 5 and 6, are formed, said stitches involvingone thread on one side of the fabric and two threads on the other side,said stitches being all formed from the single needle thread.

It must be understood that while I have shown and described only suchparts of the old machine or machines as are necessary in order to makeclear the construction and operation of my improvement, I have not shownall of the old machine or machines and with the exception of the detailsof my improvement as herein shown and described, and as hereinafterclaimed, the said machine or machines are constructed and operated asheretofore.
